Allo David, may I ask that you elaborate on the meaning of this 
paragraph. What do you mean by ''and by then it is too late''?  Too late 
for what?
Also, ''and the pump is in its final hour''. Do you mean that the pump 
is being damaged? Why should that be?
I need to understand and my knowledge of English is insufficient, as 
well as my understanding of EFI pressure systems.
Thank you. Yvon Cournoyer
